If you want to use Curtain Mode, you'll need to enable Remote Management on your Mac.
For most users, we recommend using Screen Sharing instead since it’s simpler to configure. Remote Management is only required for advanced features such as Curtain Mode.
Tip:
If Screen Sharing is already enabled, you will need to turn it off before enabling Remote Management.
On the Mac you'll be connecting to:
- Click here to open the Sharing settings.
- Turn on Remote Management.

- Click the ⓘ button next to Remote Management.
-
Under Allow access for, select All users.
If you prefer to limit access, choose Only these users and make sure your macOS user account is included.

- Click Options…

- Enable both:
- Observe
- Control

- Optionally enable Anyone may request permission to control screen if you want to allow connection requests from guest users.

Your Mac is now configured to support Curtain Mode with Screens.
